ASoC: soc-core: fix RIP warning on card removal
SOF module load/unload tests show nasty recurring warnings: WARNING: CPU: 5 PID: 1339 at sound/core/control.c:466 snd_ctl_remove+0xf0/0x100 [snd] RIP: 0010:snd_ctl_remove+0xf0/0x100 [snd] This regression was introduced by the removal of the call to soc_remove_link_components() before soc_card_free() is invoked. Go back to the initial order but only call soc_remove_link_components() once.

Use common arch_stack_walk() infrastructure to avoid duplicated code and avoid taking care of the stack storage and filtering. 2. Add sched_ra (means sched return address) and sched_cfa (means sched call frame address) to thread_info, and store them in switch_to(). 3. Add __get_wchan() implementation. Now we can print the process stack and wait channel by cat /proc/*/stack and /proc/*/wchan.

CONFIG_KALLSYMS is needed, at least the address and length of each function. Three stages when we do unwind, 1) unwind_start(), the prapare of unwinding, fill unwind_state. 2) unwind_done(), judge whether the unwind process is finished or not. 3) unwind_next_frame(), unwind the next frame. Dividing unwinder helps to add new unwinders in the future, e.g.: unwinder_frame, unwinder_orc, .etc. Signed-off-by: Qing Zhang <zhangqing@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn> 2022-08-12LoongArch: Add guess unwinder supportQing Zhang7-11/+200 Name "guess unwinder" comes from x86, it scans the stack and reports every kernel text address it finds. Unwinders can be used by dump_stack() and other stacktrace functions. Three stages when we do unwind, 1) unwind_start(), the prapare of unwinding, fill unwind_state. 2) unwind_done(), judge whether the unwind process is finished or not. 3) unwind_next_frame(), unwind the next frame. Add get_stack_info() to get stack info. At present we have irq stack and task stack. The next_sp is the key info between two types of stacks. Dividing unwinder helps to add new unwinders in the future.

Signed-off-by: Huacai Chen <chenhuacai@loongson.cn> 2022-08-12LoongArch: Jump to the link address before enable PGHuacai Chen1-8/+11 The kernel entry points of both boot CPU (i.e., kernel_entry) and non- boot CPUs (i.e., smpboot_entry) may be physical address from BootLoader (in DA mode or identity-mapping PG mode). So we should jump to the link address before PG enabled (because DA is disabled at the same time) and just after DMW configured. Specifically: With some older firmwares, non-boot CPUs started with PG enabled, but this need firmware cooperation in the form of a temporary page table, which is deemed unnecessary. OTOH, latest firmware versions configure the non-boot CPUs to start in DA mode, so kernel-side changes are needed.
